These silver coins were issued by Mahadeva, an indigenous ruler in the Punjab, in response to the silver drachms of the Indo-Greeks. As the design elements on Mahadeva's coins are the same as those on Vemaka chief Rudravarman's, these coins are attributed to the Vemaka tribe.

Mahadeva's silver coins are all rare. This type with Rajarajno legend is far more rare than the standard Rajaraja legend.

In addition, the swastika above the elephant is UNLISTED. Only swastikas above the bull are known so far.
